Answers
This are interest added on a sum of money invested. Jack will have $168.95 more than Maya in his account
Compound interestThis are interest added on a sum of money invested. The formula for calculating compound amount is given as;
A = P(1 +r/n)^nt
Given the following parameter
P =$2100
rate r = 7 5/8% = 0.07625
time t = 12 years
n =12 (monthly)
Substitute
A = 1200(1+0.07625/12)^12(12)
A = 1200 (2.4895)
A = $2987.46
For Maya
A = 1200(1+0.07375)^12
A = 2818.50
Take the difference
Difference =$2987.46 - $ 2818.5
Difference = $168.95

To find the [tex]\star\bf{radius}\star[/tex], we divide the diameter by 2:

Now that we have the radius, let's compute the area! :)

[tex]\dag[/tex] [tex]\pi =3.14...[/tex]

Have you noticed the [tex]\large\pmb{^2}[/tex] next to r? This tells us that we should multiply the radius times itself.
Now it's time to substitute the values:

Let's simplify it. The acronym PEMDAS will help us, and we won't make any mistakes in the Order of Operations! :)
Here's what it stands for:

2 is an exponent.
So what do you think we should do first?
[tex]\square[/tex] Square 47.
[tex]\square[/tex] Multiply 3.14 times 47 and then square.
That's right, we should square 47 first. :)

Now, according to PEMDAS, we should multiply pi times 2209; after multiplying, we obtain:

to the nearest whole number. (Do not write ).
Answers
Using the t-distribution, it is found that the margin of error for the 95% confidence interval is of $336.
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The margin of error is given by:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 69 - 1 = 68 df, is t = 1.9955.
The standard deviation and sample size are given, respectively, by:
s = 1400, n = 69.
Hence, the margin of error in dollars is given by:
[tex]M = t\frac{s}{\sqrt{n}}[/tex]

Step-by-step explanation:
P(A|B) = P(B|A)×P(A)/P(B)
so, in our case
P(A3|B1) = P(B1|A3)×P(A3)/P(B1) = 0.1×0.4/P(B1)
I assume that the problem definition means that A1, A2, A3 are independent and not overlapping events (hence their sum is 1). and therefore, B1 can only happen after A1 or after A2 or after A3. there is no other possibility for B1 to happen.
so,
P(B1) = P(B1|A1) + P(B1|A2) + P(B1|A3) =
